I, as a finite spirit, am conscious only by means of the divine consciousness within me, which imparts and reflects consciousness to my outward nature. My outward consciousness is like the light of the moon, which is the reflected light of the sun. The real consciousness within me is that from which I derive my external consciousness. Whenever I, as a spirit in my external consciousness, would represent myself to you, I must come into some medium of representation—some medium which will be to my spirit what the light is to my body. The medium of light will not represent me, but there is a medium which will. This, the Spirit-medium, is vastly more refined and ubiquitous than light. Standing here as a spiritual form, and giving off spiritual undulations, just as my body reflects the undulations of light, wherever the Spirit-medium extends, there my image will extend. And whenever an individual comes into _rapport_ with this spiritual medium and sustains a certain relation to me, he will be able to perceive my presence, because I am brought to his view by that which represents me. Many suppose that a person whose mind is separated from the sensuous influences of the body, or brought into the clairvoyant condition, can go to a distant place, as to London, and see an individual to whom his attention is directed. He tells me what the individual in London is thinking and saying, yet hears what is said to him here. If the individual in London were to be thrown into the clairvoyant condition, and have his attention directed to the clairvoyant here, the two could readily converse together. Space is not noticed by them, though it might be by carefully going over the space and observing a succession of objects. Being brought into _rapport_ with each other, each can observe the thoughts and feelings of the other. This is done by virtue of a simple law; and there is no mystery in it. The medium which unites my organs of speech with your organs of hearing, extends through the entire room, and my voice is as ubiquitous as the medium which communicates it. So in regard to this Spirit-medium, which is the medium of communication between the clairvoyants. By that medium, London, Canton, or any other part of the earth, is present here. Persons who mistakenly suppose that persons in the clairvoyant condition leave their bodies and make journeys to distant places, get up many curious theories to account for the body and spirit being held together. Their error arises from a mistaken conception of the actual condition of a Spirit. You see readily that a Spirit can be addressed externally only by that which represents that which addresses it. Apply to the case in hand the same law by which you see and hear me, and substitute for the media of light and atmosphere the Spirit-medium, and you will have no difficulty in understanding how it is that Spirits can be represented in different places.
